Meaning
This item allows you enable the remapping of interrupts so that a virtual machine has full
access to the interrupt requests generated by its connected I/O devices.
This item allows you to enable the cache coherency support for a virtual machine. This
allows the virtual machine access to what would otherwise be fully-hardware managed
memory caches.
This item allows you to enable the address translation services (ATS) when PCIe boards
request an address in memory.
This item allows you to enable the virtual machine's direct-memory access (DMA) requests
to access parts of your unit's non-paged memory.
